Chamfer dimensions

Minimum chamfer dimensions (fig. 1) are listed in the product tables, for the radial (r1, r3) and axial (r2, r4) directions. For metric SKF bearings, these values are in accordance with the general plans listed in the following standards:

ISO 15, ISO 12043 and ISO 12044 for radial bearings

ISO 355 for radial tapered roller bearings

ISO 104 for thrust bearings

The maximum chamfer dimensions (fig. 1) for the radial (r1, r3) and axial (r2, r4) directions, appropriate to the respective minimum values and the bore or outside diameter, are listed in the following tables:
